The answer is d as the girl is looking inn the mirror. She is 3m before the mirror . When she looks into the mirror she takes her point in the mirror to be 0m. When she observes that the 2nd girl was 8m behind her than the distance she would see the girl in the mirror would be 8 m ahead. So the 1st girl distance in the mirror would be 8m and distance of girl2 is 8m. So (6 8)m=14m
